Abstract

Summary

The genomes of and leprosy-derived corynebacteria (LDC), which have a similar base composition of guanine + cytosine 56 mol%, have been compared with those of reference bacteria of the CMN group (genera ). Genome sizes of three LDC strains were (1.2–2.5) × 10 base pairs. DNA from four of seven LDC strains examined had homology levels >60%. Two other strains had a homology of 40% when compared with the CMN strains and one strain was distinctly different. The DNA from all seven LDC strains gave 0.3–18% hybridisation with that of , 5–16% with reference corynebacteria, 5–12% with , and 2–8% with . The small size of the LDC genome and its unrelatedness to those of and organisms of the CMN group shows the uniqueness of LDC.
